Clinical Details

Official title: Treatment of Chronic Itch in Atopic Dermatitis With Oral Clonidine and Oral Naltrexone

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Reduction in Itch

Detailed description: This study will serve as a pilot study to determine the efficacy and safety of two novel oral agents (clonidine, naltrexone) in the treatment of chronic, non-experimentally induced itch in atopic dermatitis. In this study, eight subjects with symptomatic atopic dermatitis will be recruited and treated with either oral clonidine (four subjects) or oral naltrexone (four subjects) . Disease burden will be evaluated before and after 4 weeks of treatment through reporting of subjective symptomatology via surveys/questionnaire, neurometer study, and clinical assessment.
